MRT COI: Rail claws continued to dislodge even w/ cable ties
-
but then the insulator should be made of some non conductive material.think local small hardware shop can already solve problems
-
what would happen if support is mislagned..the railings will misalign too,,,all the train roller wheels might get damaged..worn out.then when it goes to a track which is normal sized width,,,it might even get derailed.

wat??? some none conductive material from hardware shop for high voltage?ya the cable tie is from some hardware shop

securing points,cable tie is not exactly used to correctly fix nuts n bolts things. -
think they have like super glue too in hardware store.dpends on who is buying the things for the problems.

dun speculate not noe the exact problem tat coz the dislodge . otherwise they could just simply replace the conponent
-
I suggest using more stronger cable ties and sticky it with solder. It usually works.

Maybe the collector shoe made too much friction to the third rail, the third rail gain too much heat and expanded, causing it to bend downward? Since the third rail doesn't have expansion gaps? Then the downward force of the expanding third rail overcomed the cable ties, causing it to break AGAIN.

Glue would be useless in this case since heat is generated by the friction between the collector shoe and the third rail. The heat would melt the glue, rendering it useless.

i dont speculate.after looking at simple thing...im beginning to think train will derail.not on that line but perhaps pther lines thru out spore.there are ceratinly more of these problems. -

how do u solder cast iron? -

thats was meant to be a joke when he said cable tie as a solution. -

u never ever use strong cable ties to fix this problem.that would be like securing a broken aircraft wing structure using cable ties too.its poor maintenance and troubleshooting method unless u have no choice.in which case u might as well use clamps.

perhaps they can try using Rubber Band or Duct Tape instead of cable tie till they come out with a perm. solution

If the thickest, strongest cable ties cannot even keep 2nos of 1/2" SS tubes holding 3000psi of hydraulic pressure on a 750 ton AHC drawworks brake lines together.
I don't expect them to last on rail claws that need to take that kind of pounding 18 hours a a day.

think its more to vibration / exertion as cable tie cannot take stress

u can try using pipe clamps

No choice, we have to continue taking mrt regardless of breakdown or no breakdown.
-
But a bit worried.
If cable ties cannot hold the claws, then what is holding the claws now?

The Fantastic Four are doing the job, charlize

more like Pathetic Four.

how about welding the claws?
or asking Wolverine to donate his claws

I think you need to stop watching too much cartoons.

or Magneto to "magnetise" the claws
